Resilient Coupling
Boson Resilient Coupling basically comprises a Grid Spring which connects two hubs - one on the driving and other on the driven shafts - through axially cut grooves around the peripheries of the two hubs. The spring, which is of special design compatible to the required characteristic of the system, form a series of resilient bridges along the grooves. The grooves are flared to allow the grid members long flexible spans under normal loads as well as better support by the sides of the grooves under overload conditions.

FOR USE ON HORIZONTAL SHAFTS ONLY
